Internal combustion engines are designed for a fuel with a specific consistency. The fuel is made from raw materials that have various consistencies so they have to be refined. The refinement is complex and thus expensive, which leads to it being centralized. Gasoline is refined from crude oil.

That or something like Flex Fuel or Multifuel etc, may just push this info onto all of those
